It’s pretty clear that the rules say that what you have to do to create a demon is find a soul on the astral plane, sever the tethering cord, infuse the astral body with mana (e.g. through the binding spell) and do some sort of forming. In essence it seems possible to do this not only to inhabitants of other worlds but also to the inhabitants of Astlan. So. Has anyone in the world thought of trying that? Surely there has to be a wizard out there that’s twisted enough to come up with an experiment of substituting an unbound demon with a human soul.
